Related works on the atomic norm suggest using the CVX toolbox to solve the SDP (REF ) [1]}, which can be time-consuming for large-scale problems.
To solve (REF ) in an efficient way, we develop an algorithm based on the alternating direction method of multipliers (ADMM) algorithm [2]}.
The ADMM algorithm integrates the augmented Lagrangian method with the dual ascent method, which usually shows excellent efficiency in solving large-scale problems.
